MOTHPROOF MOHAIR Filed MaICh 20, 1951 Application filed expensive to apply, which does not reduce the flexibility of thev Jfabric land Which is unbroken by the stretching' of the fabric. incident to its use in upholstering.

Other objects and advantages of theinvention will become yapparent Yfrom the following detailed description taken in l conjunction with the accompanying drawing` in which:A

20 Figure l shows on anenlarged scale a piece of fabric such as mohair viewed from the 1anderside and having' portion thereof treat-ed in accordance with the .present invention.

Fig. 2 is a sectional View of the mohair shown in Fig. l but on a greatly enlarged scale. V

3 is an enlarged View of one et theY bundles of hair bent into the. shape which it resumes in the Weaving process.

llhile the invention is susceptible el" various modifications and alternative construcn tions. l have shown in the drawingand Will.

herein describe in detail the preferred embodiment. but it is to be understood that l Vdo not thereby intend to limit `the invention to the specific. form disclosed, but intendto cover all modilieations and alternative constructi ons falling- Within the spirit and scope ot the invention expressed in the appended claims.

s'shown in the drawing, modern mohair consists ot a facing; cozmorising` bundles 5 (Fig. of relatively short animal fibers goats-liair bent into substantially U-shape With their intermediate portion passing beneath a Warp thread then over two Warp threads 'land finally under a third 50 Warp thread 8. all or" which Warp threads are held together by cross threads 9. rflous the Aside of the mohair.

, leaving` the latter bare.

'tree ends 'the bundle of liber-s are heldin parallel relation by a cloth backing formed by the Warp threads and thewthreads 9. llhen the cloth is thus Woven, the bights l() ofthe liber bundles are exposed on the back y Moths and theirlarvae attack the fabric by boring through 'from the front andthen turning to Work on the baclr .side of the liber when the/,latter is used in upholstering.. heir attack is centered upon the bights lO Weich when completely severed bythe moths allow `the ends of the bundles to be pulled out of the Warp threads Referring now to Figs. l and 2, the invention in its preferred `form contemplates the covering of the back surface otlthe mohair clotli termed as above described with a thin coei; ensiye coating or backing' l2V otcotton 'fibers which are so closely matted together that the high-ts l0 ofthe `hair bundles are eectuallycovered. y

l'n manufacturejthe coat-ing; lmayvbe formed by ii 1stt-covering' the-back surface of the mohair cloth with a. suitable adhesive ll. Then the cotton i'ibers are pressed againstv the adhesive which' reta'ns a sutlicient quan-- tity ofthe fiber to term the coating l2 which, *being composed otyegetable material, entangle the nippers of the moths and can-not be penetrated by. them. The mohair is thus rendered motlrproot.

lnasmuchas the-'protecting' fibers of the coating l2 are merely matted` tog` therv the flexibility et the vn'iohair is. not impaired materially. Such a coating permits the mohair to be stretched readily as is necessarily done in uphoh s :ing andremains intact after such stretching. The thclrne'sso' the mohair is notmaterially increased With. such a mothproot coating; and can be 'folded as may be required 17Tithout*leaving-i' bulky seams. i

Instead oi using an adhesiye as above described, lAe cottiV fibers constituting the protect-ing coating vmay be Woven directly intol the mohairkand so hel-d by the Warp hreads and the threads 9 that they Will cover` L L the bights l() oi uw hair bundles which would otherwise be exposed on the underside ot the mohair.
